How to test email sending using Rspec?
email-spec looks like a good library
What do you want to test exactly?
Do you want to test that the email is indeed really sent?
I don't recommend it as it will make your test slower and it really depends on the machine you are using to run your tests (network connection, smtp server).
What I usually do is make sure the controller action / model / rake task which send emails runs correctly (meaning without error, I stub the final send call).I also make sure the body, title and recipients for the mail are correct.
Edit:
Not directly related to testing but I just came over this article.
I like his point of view of using the model to send emails.So to explain a little more in details:
I would use the controller to set up view variables like@body, @title, @recipient.
So I would test that given correct parameters the mail template (which is a view) is correctly rendered.This is were mistakes can happen from my point of view.
I will update this post with example when I am back home later today.
